When i turn on the heater it just blows smoke

When we turn on the heater it blows out smoke and some kerosene comes out of the front of it instead of the flame that is suppose to come out. We have already tried to dry the spark plugs and other parts that we can reach.

Re: when i turn on the heater it just blows smoke

If the unit has a high voltage transformer that ignites the flame. ie it has a heavier wire plugged into a spark plug or igniter. the coil is likely bad..... it should arc as soon as it is turned on. later models have a heater that gets very , cherry red, hot and that ignites the fuel. take the top cover off and you should be able to identify which you have. coil sets right under fan. one heavy wire and two light wires as the primary. light wires at about 12 ohms and heavy wire to chassis in the k ohms.

Re: when i turn on the heater it just blows smoke

According to desatech who makes reddy heat, the air compressor on the back of the fan should put out no more than 3.5 psi to the nozzle. you could also check the air path through the combustion chamber. sounds to me that the nozzle isn't atomizing the fuel but its coming out in a stream. the nozzle is supposed to make a conical pattern if the air pressure is correct.

Reddy Heater kerosene 110,000 btu . plup it in, fan runs, blows smoke out the front, leaks kerosene also from front, i have cleaned photo cell, replaced plug, cleaned filter and checked lines for cracks,...

Just because there is fuel & spark does not necessarily mean there will be combustion. The fuel must be delivered at the correct pressure, the correct volume, and must be delivered as a fog- not a mist.

My suggestions:
  1. set the pump pressure
  2. be sure the fuel filter is clean
  3. be sure no air leaks or vacuum leaks
  4. Desa recommended annual replacement of the nozzle. They wear out. When was the last time yours was changed?

Heater turns off leaving lots of smoke and is hard starting

If this is a kerosene heater,the wick is most likely not adjusted up enough,or the wick is contaminated.The fuel could be contaminated also.Remove the old wick and replace it,and refuel it with clean kerosene,after you pour the old out.

Pro 110, runs 10 min., blows white smoke ,shuts off

the first thing you need to do is go back to useing K1 kerosene, diesel fuel not only burns dirty but also has a tendency to gel up in cold weather which could be makeing it hard for the heater to draw the proper amount of fuel. To reset the pressure you will need a gage, it should run at about 6-7 psi. you can order a pressure gage from mr. heater online, they are by far the cheapest I have found as they are the actual manufacturer or call 1-800-251-0001

clean all of your filters and the spark plug and go back to useing K1 kerosene. Diesel fuel has a higher ignition temp. burns dirty and has a tendency to gel.
